GEORGE N. HELFRICH, OF GLENDALE. NEW YORK, ASSIGNOR TO THE UNITED STATES PRINTING AND LITHOGRAPH- COMPANY. A CORPORATION OF OHIO- Application filed December 3. 1920. Serial No. 428,047.

To all whom it may concern Be it known that I, GEORGE N. HELFRICH,

av citizen of the United States, residing at Glendale. L. 1., in the county of Nassau and State of New York, have invented certain new and useful Improvements in Boxes;

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appe-rtains to make and use the same.

This invention relates to improvements in paper boxes made from one piece of material which is laid out in such manner that it may be readily folded into the form of a box.

One of the objects of the invention is to provide a box of the character specified in which improved means are provided for maintaining the box in its built up condition.

Another object of'the invention is to so cut the material from which the box is to be made that the box shall resemble a socalledwrapped box, that is to say, a box which has been wrapped or covered with a decorative wrapper or the like for the pur' pose of enhancing its appearance. In covering a box with a wrapper it is customary to fold the same at the ends of the box in such a manner that the edges of the same converge away from the bottom of the box so as to present a neat and attractive package. My invention makes possible the attainment of this desirable result without the necessity of employing a separate wrapper and hence reduces the cost of manufacture and time in making the same. Other features of the invention will appear from the detailed description thereof taken in connection with the accompanying drawings in which:

Figure 1 is a plan view showing the manner in which the sheet of material is cut or laid out inorder to form my improved box;

Figure 2 is a. view in perspective of the folded box, one end of the box being partly unfolded for clarity of illustration,' the other end of the box clearly illustrating the converging edges which serve to give the box its wrapped eflect;

Figure 3 is a vertical cross sectional view taken on a line passing through the middle of the box;

Figure 4 is a view similar to Fig. 3 showing one box section telescoped over another sect on to form a closed package; and

Figure 5 is a view similar to Fi 2 but showing a slightly modified form 0 the invention as it relates to making the endclosure of the box.

By reference to Figure 1 it will be seen that the blank sheet of material is outlined to form a rectangular base or bottom member 10. Primary side walls 11 and 11' extend laterally of the base 10 and extending from said primary walls are secondary walls 12 and 12 which are of a width substantially the same as that of the primary walls so that when the secondary walls are folded over into position contiguous to the primary walls as upon crease 11 the complete side walls formed by the primary and secondary walls will be of substantially the same height as will "be readily understood;

Projecting laterally of one secondary wall as 12' is a false base or bottom member 13, a crease or line 12 extending longitudinally between the same. This false bottom is preferably of a width substantially the same as that of the true base 10 for a purpose that will presently appear. At this point it may be observed that the lengths of the base 10, the primary and secondary side walls and the false bottom 13 are substantially the same.

Extending laterally from the secondary wall 12 is a comparatively narrow tab 14 and the length of this tab is considerably less than the length of the side walls, this lesser length being had by cutting away a section of material at each end of the tab thus leaving what might be termed a step 15 at the ends of the upper corners of the secondary wall 12. The purpose of this arrangement will presently appear.

Referring to the secondary wall 12 and false bottom 13 it will be seen that the. material at each end of the crease 12 which separates the two members is cut away inwardly of the outer edges to form notches 16 which are substantially V shaped in plan, the depth of the notches being substantially equal to the longitudinal incut of the steps 15. From this it will be seen that the distance between the bottoms of the notches 16 is substantially the same as that of the tab 14. When the secondary walls are folded over to form the interior side walls of the box, the tab 14 is bent at right angles to its wall 12 and projects inwardly toward the centre of the box. The false bottom 13 is also bent at a right angle and extends inwardly across the true bottom 10 of the box, the outer edge of the false bottom overlying the tab 14 so the latter is thus held down against the bottom 10. The resultof such folding is to provide, through the instrumentality of the ste s 15 and notches 16, shallow wells W at t e fourbottom corners of the box for the purpose of receiving cooperating locking elements which will now be described. f

The ends of the box are formed or la1d out in the following preferred manner: The sheet of material is creased or outlined to form the end members 17 and 17 and extending outwardly from these members are the secondary walls 18 and 18'. Extending from these walls are tabs 19 and ,19 the width of the tabs being only slightly less than the depth of the recess or notch 16 or tread of the step 15 so that the termlnals thereof may be readily inserted into the wells before mentioned.

In order to give rigidity to the end of the box and to provide for the wrapped appearance hereinbefore mentioned, and also to provide for completely sealing the corners, the material is twice creased as at 17 and 17 both creases extending from the corners of the bottom to provide the sections 20 and 20 and sections 21 and 21', the creases 17 being made at an angle relative to the crease 17 intermediate the bottom and the primary end depending upon the angle of inclination desired to be shown upon the finished end to produce the appearance hereinbefore referred to, while the crease 17 a unequally bisects the parts intermediate the primary ends and sides. llt will be understood that both ends of the box are similarly laid out and creased. v

The sheet is folded into box form substantially in the following manner: The primary wall 11 is bent upwardly at an angle of to the base 10; the secondary wall 12 is then bent inwardly throu h an angle of 180 and the tab or flap 14 15 then bent inwardly at an angle of 90. The other side of the box is formed in a similar way, the false bottom 13 however extending across the width of the box and at its outer edge overlying the tab or flap 14. The ends of the box are now formed by bending the material on a crease between sections 20 and 21 (and 20' and 21) and then bending, the end 17 upwardly at an angle of 90 to the base 10 andthereupon bending the wall 18 at an angle of 180 .over the end sections and then bending the tab or flap 19 at an'an le of 90 and pressing the ends of the same" own into the wells or pockets W: hereinbefore mentioned. Inasmuch as the length of the tab '19 is substantially the same as the distance neeaare between the prima walls 11 and 11' and greater than that etween the secondary walls 12 and 12' it will be readily appreciated that the tabs 19 are edectually held in said wells against displacement and consequently the box as a. whole is efl ectually maintained in built up condition.

As modification of the invention l may, instead ofproviding the creased end sections 20 and 21 and 20 and 21' provide sections 0; and b which are slit from a point extending from the corner of the base along the line of the crease which defines the width of the base 10. This arrangement is illustrated in Figure 5 of the drawings, and is perhaps more appropriate for use as the container portion of the box whereas the construction first described is preferably the box cover, although I do not restrict myself to this particular use of the two c0n structions.

Referring again to the preferred form it will be seen that the wall 18 (and 18'.) is out at its corners adjacent the ends 17 (and 17') as at 22 so as to leave the wall 18 (and 18) substantially the same width as the base 10. This arrangement serves to give rigidity to the box inasmuch as the prlmary walls 11 and 11' are allowed to come into direct contact with the'side edges of the said wall 18 (and 18).

Having thus described the invention what I claim as new and desire to secure by Letters Patent is: f

1. Abox made from one piece of material and comprising a base and two side walls, means for closing the ends of the box and simulating a wrapped box comprising a member rising from the base of the box adjacent the terminals of the side walls, said member having its side edges converging away from the bottom of the box, a secondary member secured to the first mentionedmember and adapted to be folded in substantial parallelism therewith to form the inside of the box, said secondary member being of a width substantially the same as that of the box and adapted to serve as side wall supports to prevent the inward collapse of said walls, means connected to the ends of the walls and passing between the two mentioned members whereby a reinforced end-closure is obtained, and means for removably securing the said second mentioned member in locked position with respect to the sides of the box.

2. A box made from one piece of material folded to form a base and side walls, in combination with parts partially closing the ends of said box and a part integral with the last mentionedparts having inclined ends rising from the base of the box and abutting said first named parts, a wall member extending from the upper edge of said integral part and folded over the parts llll whichpartiall close the ends of the box, said wall mem er for the major part of its width being substantially the same as that of the box and engaging the side walls of the latter, and means for removably securing said wall member in a fixed position.

3. A box blank comprising a substantially rectangular portion which is creased to form an intermediate rectangular portion of a lesser area to serve as a base or bottom, the margins or borders resulting from such creasing serving as primary and secondary side walls, as end-closures and as corner seals, the secondary wall sections comprising. sections centrally located and projecting beyond the primary wall sections, one of said secondary wall sections havin a longitudinally extending tab of less length than itself, the opposite secondary wall section having a false bottom projectin therefrom, there being notches at each en of the line separating.the false bottom from the adjacent section, and projections of sub stantially the same width as the outline of the base projecting from the end-closures, said projections being creased near their outer edge, the corner portions adjacent the primary side and end walls being adapted to be folded inwardly to constitute corner seals, the line of fold between the seal and the end wall inclining outwardly.

4. A box comprising a bottom, sides and ends, said bottom, sides and ends being formed from a substantially rectangularshaped piece the part intermediate the adjacent sides and ends being adapted to be folded upon itself on a line extending from the corner of the bottom and unequally bisecting said part, in combination with extensions formed on said sides and ends adapted to be folded inwardly to form false or secondary sides, ends and bottom and to interlock to maintain the structure in folded position. v

5. A box comprising a bottom, sides and ends, said bottom, sides and ends being formedentirely by creasing; the parts be tween adjacent sides and ends being creased from the corners of the bottom to form the ends of said sides and ends and being further creased diagonally from the corners of the bottom to unequally bisect said parts, in combination with extensions formed on said sides and ends adapted to be folded into the box to form false or secondary sides and ends and to interlock to maintain the box in folded shape.

-6. A box made from one piece of material comprising a bottom, primary side walls, secondary side walls extending inwardly and extending in proximity to the bottom of the box, the corners of one of said secondary walls being cut away, a false'bottom extending from one of said secondary walls. a re -entrant portion at each of the ends of the fold line between the false bottom and its attached wall, an end-closure for the box comprising a main member extending upwardly from the base of the box, collapsible members between the said end-closure and the primary side walls, a secondary endclosure connected to the said closure memher and bent over said collapsible members and having an extension adapted to rest on the false bottom of the box, the ends of said extension underlying the secondary walls at the cut-away and re-entrant portions.

In testimony whereof I affix my signature.
